Hullo Jeremy:
You are missing a probe because it is not in the tutorial.
You should add it, if you want to see local probes. The method is already in
the accessing protocol, because energy is an attribut of forager, and you
should change the method and move it to probes protocol.
energy
"Getter accessor with default value = 50 "
energy isNil ifTrue:[energy := 50].
^energy
and you should see it.
I am also a beginner, an experienced beginner, but always a beginner, and
I was also trying to make the tutorials, for the n time.
I have had the problem that typing the program with another name, such as
ECEC or MiPrimerModelo, the maps where missing, and I had to copy them from
MyFirst...\maps, but I still don't arrive to see the foragers on the screen.
Perhaps we can think of a sub\cormas\network for beginners from level 0 to
level 1, and try to cooperate by encouraging ourselves, and perhaps
following a common learning program for some time?
